Head gasket issues and car overheated

- Oxford, IA, USA

NHTSA Vehicle Safety Complaint Vehicle: 2019 Honda Accord 1.5T Engine: 1.5-liter Turbocharged (L15B7) Mileage at Failure: 88,000 miles Issue: Blown Head Gasket / Coolant Leak / Engine Stalling Summary of the Problem: At approximately 88,000 miles, my 2019 Honda Accord 1.5T began exhibiting signs of a coolant leak and engine performance issues. After diagnosis by a certified mechanic, it was confirmed that the head gasket had failed, causing coolant to leak into the engine. This led to overheating and a dangerous engine stall while I was in active traffic, posing a serious safety risk. Safety Concern: The vehicle stalled unexpectedly in traffic due to the head gasket failure, putting me and surrounding drivers at risk of a crash. A blown head gasket can cause sudden overheating, misfires, and loss of power, all of which jeopardize the safe operation of the vehicle. This occurred without any warning lights or prior symptoms, making it even more dangerous. Repair Cost: The repair for the blown head gasket and associated engine work cost me $3,800 out of pocket, despite the vehicle being well maintained and relatively low mileage for this type of failure. Maintenance & Vehicle History: The car was serviced regularly according to Honda-??s recommended schedule. There were no prior signs of overheating or misuse. The stall happened suddenly, requiring the vehicle to be pushed to safety to avoid blocking traffic. Wider Problem Indication: This issue appears to be widespread among 2019-?"2021 Honda Accords with the 1.5T engine. Many owners report similar head gasket failures, indicating a potential defect in the engine-??s design, materials, or thermal management. Requested Action: I respectfully request that the NHTSA investigate this issue as a safety-related defect, and that Honda be required to issue a recall, extended warranty, or reimbursement program to address these premature and dangerous failures.

In December 2024, all of the lights on my dashboard came on & my car would not accelerate. The code indicated that it was a "Cylinder 2 Misfire." I replaced the ignition coil for cylinder 2 but my car continued to have the same issues. I had all 4 ignition coils replaced and all 4 spark plugs. In March 2025, all of the lights on the dashboard came on again with the car not accelerating properly. I had it looked at again, was told that it was a "Cylinder 2 Misfire" again but all 4 ignition coils were working properly. A spark plug was replaced at that time. Then, in May 2025, the car did the same thing with all of the lights coming and the car would not properly accelerate. The car again read that there was a misfire with "Cylinder 3" but all of the ignition coils worked properly. I had the fuel injectors replaced and another spark plug replaced. The car didn't even make it 24 hours before all the lights came on again. The RPMs in the car now go past "3" but will not accelerate & shift gears. The Honda Dealership has advised me that the head gasket needs replaced. My car has 74,000 miles on it. I had it inspected April 2024 with no head gasket issues & the car was at 64,000 miles approximately. So, in 8 months' time, the head gasket was blown & the car is well under 100,000 miles. I have been told that the engine my car has, 1.5L turbo with Honda has had this issue to the extreme that a class action lawsuit has been filed as Honda refuses to do any time of recall or assist with repairs. I literally had to drive with my 4 ways on to avoid being hit in an intersection due to the inability of my car to accelerate. The NHTSA needs to investigate Honda & determine if they are defrauding consumers by refusing to issue a recall due to this common & dangerous issue. I have owned 7 hours in the 30 years I have had a driver's license & never once had a head gasket issue or any issues to this extreme. I have never replaced a head gasket in any car that I have owned.

The problem has been confirmed by a certified Honda dealership. It The vehicle has been inspected by the Honda dealership. Symptoms that I have not confirmed to be related to the issue are missing coolant without any leaks.

While driving my 2019 Honda Accord at approximately 65 mph on the highway, the car suddenly lost power, went into limp mode, and the steering wheel locked up. I was unable to turn or control the vehicle, which resulted in another car crashing into me. I sustained injuries in the accident and required medical attention. The incident was extremely dangerous and could have been fatal. After being towed to Russell & Smith Honda, they confirmed a blown head gasket was the cause of the failure. This issue is already the subject of a class-action lawsuit due to known design flaws in the 1.5T engine. Honda only offered partial assistance, leaving me responsible for thousands in repair costs. This vehicle is unsafe and needs to be investigated immediately.

My vehicle makes a humming noise while driving. The humming noise is heard about 3 times in a row then a pause then 3 more hums, while driving but seems to be louder at around 50mph +. My vehicle has 56k miles an it and it has had that sound since I purchased it used with about 30k miles. I have been doing research on it but have not been able to figure out what causes the humming noise nor what the resolution is to fix it.
